Dentists existed in Stone Age !

I am sure that you already asked your self how people took care of their teeth when there was no dentists and no pain killers. Stone age people in Pakistan were using dental drills made of flint 9,000 years ago, according to researchers. BBC News reports the discovery in Pakistan of stone age teeth that bear clear signs of dental drilling. Flint drill heads are apparently abundant in the Mehrgarh region, near Quetta in Pakistan, but this is the first evidence of their use on humans. The scientists concluded that the practice apparently disappeared from the achaeological record after 1,500 years.
